how to call a predefined target or macroin build.xml from Custom
Ant task
Hi,
I am looking to call a Macro defined in the project though custom task.
Similarly calling of target.
Both macro and target are defined the build.xml and my java based custom
task should be able to call it with min overhead.. i.e with the same
overhead as calling the macro from build.xml or calling one target from
other either by depends.
Regards,
Raja Nagendra Kumar,

macro = ...createTask(...);
for(...) {
macro.setDynamic(...)
macro.execute();
}
This should work. My example reused that too (1st with default value, 2nd run with custom value).
You have to ensure that no required values are "deleted" in further runs. But if all runs require
the setting of the same parameters (maybe with different values) this should be enough.

Thank You Jon, this rocks..
instead of createTask() every time, is there a way to reuse the already
existing one (either may be created by xml files or with in other script
file..)
Not sure how memory and cpu intesive is createTask() specially when it is
for loop (in our case this macro is run many times).

but don't find a way to execute the macro. Any pointers pl.
